remarques This is a great example of the vintage Blancpain Fifty Fathoms model with a beautiful original 3 6 9 dial . The case is excellent and had never been polish, the 17 jewel automatic movement is very clean. It is very difficult to find the Aqualung in such nice condition. The watch is signed by Blancpain on the dial, dust cover, case and movement. Circa 1950s.
